The suspended crunch is an abdominal exercise performed with the feet in the stirrups of a suspension strap system. It targets the muscles of the core, most prominently the rectus abdominis or "six-pack" muscles, but also taxes the shoulders and deep core muscles.
Benefits
Similar to a mountain climber, but with more constant tension on abs
Intense stretch and contraction of abdominal muscles
Powerful isometric work for shoulders and upper back, similar to a plank
